Lower hinge housing and upper articulation housing mechanical attachment, to form the pivot fitting with pivot axis.When the revolving force around pivot axis is applied to top 120, pivot fitting contributes to the relative motion of top 120 opposing lower portions 140 around pivot axis X-X'.
Described lower hinge housing comprises a pair hinged end.This limits a pair pivotal arm keeping upper body to hinged end, to allow top around the relative pivoting action of pivot axis.Each hinged end comprises end plate, and end plate longitudinally upwards extends towards the direction connecting housing away from battery, to limit the height of lower hinge housing from handle portion.End plate extends to the both sides, front and back of pivot axis, to limit the width of lower hinge housing.End plate is parallel to each other and its spacing is suitable for snugly receiving upper articulation housing.End plate collectively defines the outer wall of lower hinge housing, and upper articulation housing is received between described outer wall.
Each hinged end all comprises pivot section 148.Pivot section 148 is given prominence to from the center of end plate and is extended transversely in the hinge hole 126 upper articulation housing.This extends and coaxial alignment toward each other to the pivot section 148 of hinged end, to limit the pivot axis of the pivot fitting connecting top 120 and bottom 140.
As shown in Figure 10 and Figure 10 A, arrange a series of recess 150 around pivot section 148 with annular shape.This series of indentations comprises N number of recess, and each recess has definite shape, described shape makes when the locking devicen with upper body 122 mechanical attachment or mechanical connection is received in one of multiple recess 150, and top 120 can be kept one of multiple inclination angle place by relative to bottom 140.Described inclination angle is the angle of the longitudinal axis on top 120 and the longitudinal axis of bottom 140.The longitudinal axis on top 120 is along the axis of upper body 122 longitudinally through elongated upper body 122, and the longitudinal axis of bottom 140 is along the axis of lower case 142 longitudinally through elongated lower case 142.In some cases, inclination angle can be expressed as the angle between the longitudinal axis on top 120 and pivot axis.
Recess 150 distributes ringwise around pivot section, and pivot section is the center of annular, makes each recess 150 corresponding with one of multiple inclination angles on top 120 relative to the inclination angle of pivot section.N number of recess 150 defines N number of discrete inclination angle, and top 120 can remain on these discrete tilting position.When top 120 is moved by N number of recess 150, top 120 will by N number of step angle and angle of coverage range Theta.Each step angle comprises angle
wherein n is 1 to the arbitrary number in N, and N is integer.
9 recesses 150 are had, so N=9 in the example shown in Figure 10 and Figure 10 A.Top 120 is θ=144 ° around pivot axis through the total angle coverage of the pivoting action of 9 recesses 150, and the scope of each step angle
it is 15 °.Top 120 can remain on one of the inclination angle configuration of 9 shown in Fig. 7 place.
Do not losing in general situation, the angular coverage of each step angle can be set to difference as required.The size of suitable exemplary step angle is between 12 °-20 °.The sum of recess 150 can change, and suitable exemplary range is 8-15 recess.Total angle scope or maximum angle scope also can change, and suitable exemplary range is between 60 °-180 °.
Locking devicen and a series of recess 150 cooperatively interact to limit maintaining body, so that top 120 is remained on one of multiple inclination angle place.In appropriate circumstances, inclination angle is also referred to as inclination angle configuration.
The example of the locking devicen shown in Figure 10 and Figure 10 A comprises latch assembly 162, and latch assembly 162 comprises lock pin and spring.Latch assembly 162 is arranged on top 120, and when assembling, lock pin is pushed towards recess 150 by the spring be associated.When lock pin is received in recess 150, top 120 is just maintained at the angular configuration place limited by this recess 150.
Lock pin comprises the round end received by recess 150.When being applied above the revolving force of predetermined threshold to upper body 122, the round end with a side contacts of recess 150 can being driven, make its thrust overcoming spring and leave recess 150.When the round end of lock pin is received by recess 150 again, if revolving force disappears or revolving force is less than threshold value, so lock pin will be parked in this recess 150.The spring thrust being applied to lock pin is designed so that the shortage in weight on top 120 leaves recess 150 to drive lock pin.
Battery connects housing and comprises battery snap close to downward-extension, removably to receive battery pack 160.
In certain embodiments, recess can be arranged in upper body, and lock pin can be arranged in lower case.In certain embodiments, maintaining body can comprise ratchet mechanism or pin adds holes mechanism.
In use, when upper body is in certain angular configuration place, user can operating power switch to be switched on or switched off the power supply of LED component.When needs change angular configuration, user can apply revolving force to required direction of rotation.Such as, user can hold top and apply revolving force to it.When the revolving force applied exceedes predetermined threshold, will overcome confining force and make ionized motion cross recess, during in revolving force disappearance or lower than threshold value, lock pin will be received in recess.Top can arrive another extreme angles position shown in Fig. 3 from the extreme angles position of shown in Fig. 1.Top can move into place another angle position between these two extreme angles positions from an angle position between these two extreme angles positions.
The example of battery pack comprises Li-ion batteries piles.The weight configuration of battery pack is be enough to the top that all possible angular configuration lower support between extreme angles configuration hangs outward.
Although invention has been described for reference example, scope of the present invention is not limited to described example.Such as, although with LED as an example, can also use and there is enough light intensity and the illumination component of brightness characteristics.
